Roof of Canada arena needs repairs due to ice buildup

The roof of the Gravenhurst Centennial Centre in Ontario needs to be repaired after ice accumulated on the roofing interface. The repair calls for installation of additional waterproofing on a portion of the roof, according to Wayne Rosberg of CS&P Architects. "The simplest thing [in original construction] would have been to say let’s remove the existing roof [and build it as one piece]. It doesn’t work; the old roof is difficult to tie in to," Rosberg said.
